#ansible #encrypt #devops #cloudopz

  • Ansible Vault encrypts variables and files so you can protect sensitive content such as passwords or keys rather than leaving it visible as plaintext in playbooks or roles.

  • 5 steps or less to quick start with ansible vault

1. Create password stored file to hold the master key

passwd_file

~: cat passwd_file

2. Generate encrypted password and data conent

  • Password for ssh-login 
 $ ansible-vault encrypt_string --vault-id vagrant@passwd_file 'rootroot' --name vagrant
vagrant: !vault |
          $ANSIBLE_VAULT;1.2;AES256;vagrant

3. Create ansible task to test decryption

  • test.yml: Variable my_data_encrypted as encrypted value 
⚡ $ cat test.yml 
---
- hosts: all
  become: true
  vars_files:
    - var.yaml
  tasks:
    - name: ansible vault test
      debug:
        msg: "{{ my_data_encrypted }}"
Enter fullscreen mode Exit fullscreen mode
  • inventory: variable vagrant as the encrypted value 
⚡ $ cat inventory 
[ubuntu]
192.168.121.21

[all:vars]
ansible_connection=ssh
ansible_user=vagrant
ansible_ssh_pass={{ vagrant }}
Enter fullscreen mode Exit fullscreen mode

4. Run ansible-playbook 

⚡ $ ansible-playbook test.yml --vault-id dev@passwd_file -i inventory -e @var.yaml
ok: [192.168.121.107]
 ___________________________
< TASK [ansible vault test] >
